In this article I will review the CEMA Bearing SRC-TT-B019 Bottom Bracket Tool, that I’ve used to install a CEMA Bearing Interlock BB86-BB92 Bottom Bracket on the Scott Scale 925 mountain bike. I will try to provide my view on the quality, design and my practical experiences.

Key features CEMA Bearing SRC-TT-B019 Bottom Bracket Tool
On the product page of the CEMA Bearing SRC-TT-B019 Bottom Bracket Tool you can read a brief description that is more about bottom bracket types, that about what the tool actually does.
To remove and install CEMA bottom brackets BSA24, ITA24, T4724, T4725, and Interlocks BB86/89/92, BB3024, BB3025, PF3024, PF3025, RBB3024, RPF3024, BB30A24, PF30A24, OSPF3024
I prefer the SRC-TT-B019 Bottom Bracket Tool over the CEMA Bearing Bottom Bracket Wrench with product number SRC-TT-B020 (which I also own). I connect the 1/2″ drive on the backside to the Wera Zyklop 8000 C for 1/2″ sockets, where this ratchet has a 72 teeth ratchet mechanism that allows for a low return angle of 5°. So you can securely tighten the longer Interlock Bottom Bracket cup. The connection of Wera Zyklop ratchet and CEMA Bearing SRC-TT-B019 is firm and rock solid.
The side surface of the SRC-TT-B019 has a rectangular grid engraved in the surface. That allows for solid grip not only to guide the tool, when tightening the interlock cup with the Wera Zyklop ratchet, but also in the first part, when you hand-tighten the cup (and when you need to feel that the threads are properly engaged). Small details but very helpful. Other tools don’t have this extra grip.
Another unique feature that I like is the included adapter from 1/2″ drive for use with a ratchet to a 8 mm long hex key. While you would need something like The CEMA branding is laser edged in a grey finish, so that looks nice and clean on the tool.
The short non-drive-side cup, needs to be pressed in just like a press-fit bottom bracket. For that I used the CEMA Bearing Bottom Bracket Replacement Tool which is a tool set. 🙂 A necessity to remove old bottom brackets without putting peak-loads on your carbon frame.
Finally I’ve used the CEMA Bearing SRC-TT-B019 Bottom Bracket Tool to tightening the centerlock lockring of the Cyclotech Endura Centerlock Disc Brake Rotor (on the front wheel). Simply because the tooth profile on the tool inside is the similar. However after purchasing a specialized tool, the Wheelsmfg CL-Socket for Centerlock lockrings, I will not use the SRC-TT-B019 anymore for this use case.
Concluding thoughts and wrap-up
The price-point of the CEMA Bearing SRC-TT-B019 Bottom Bracket Tool is 28,00 which to me is a fair price for a quality product. Of course you would need to have a proper quality ratchet as well, preferably with a fine tooth mechanism.
Before you can install a CEMA Bearing Interlock BB86-BB92 Bottom Bracket you also need to remove the old bottom bracket. The CEMA Bearing Bottom Bracket Replacement Tool is my preferred companion toolset for that. The version that I’ve used consisted of a similar tool made from red plastic material. The current version with product number SRC-TT-B006D has also metal tools that are very similar to the CEMA Bearing SRC-TT-B019 Bottom Bracket Tool.
